Patent DE-3741744-A1 (DE)
Title: Shutter door having a shutter-door leaf which can be displaced in lateral guides
Inventor: DOERING ERICH DR
IPC: E05F1/16
Filed: 1987-12-09
Abstract: In the case of a vertically opening sectional shutter door or the like, weight compensation takes place via lateral tension-spring arrangements (11). Without complex supplementary measures in terms of motor drives, different forces come to act on the two sides of the shutter-door leaf (1) in this arrangement, which result in synchronisation difficulties. These problems can be eliminated in that the upper deflection rollers (16) of the tension members (13) for the weight compensation are connected in a rotationally fixed manner to a common upper shaft (18), and suitable means for a simultaneous rotation of the shaft (18) are provided on the tension members (13). In particular when using wire cables for the tension members (13), a positively locking simultaneous rotation can take place in that the wire cable is subdivided, in the region of the deflection roller (16), into a spring-side tension element (13a) and a shutter-door-leaf-side tension element (13b), whose ends are each fastened on the deflection roller (16) which is configured as a reel. In this manner, weight compensation is possible without any difficulty even with a tension-spring arrangement (11) on only one side, and, in addition to any desired type of motor actuation, provision may also be made for hand actuation of the vertically opening sectional shutter door without any synchronisation problems arising. <IMAGE>

Title: High-voltage relay circuit
Inventor: GUENZKOFER ALOIS
IPC: A61N1/39
Filed: 1989-04-03
Abstract: In the case of some medical devices, stray electromagnetic radiation is produced which has a detrimental effect on the reliability and operational safety. In the case of defibrillators, a current pulse is supplied to the body of the patient via two electrodes, in order to overcome disruption of the action of the heart. Energy is stored in a capacitor within the defibrillator and is available for the shock pulse via the two electrodes. Conventionally, a high-voltage relay is used for relaying the current pulse to the electrodes. According to the invention, the contacts 2a of the high-voltage relay 2 are closed currentlessly, since the current pulse is triggered only after closing the contacts by triggering of the triac circuit 3. By virtue of the invention, the possibility is achieved of switching the defibrillation shock with current intensities of up to 200 amps, without stray electromagnetic radiation being produced as a result of spark formation or electric arc discharges. <IMAGE>

Title: Muscle-powered short-flight aircraft
Inventor: KUENANZ RICHARD
IPC: B64C31/04
Filed: 1989-04-10
Abstract: Until now, there has never been any popular sporting apparatus in the world which, on the one hand, has allowed short, risk-free leaps into the air while, on the other hand, also being capable of being used equally well for slimming purposes. Both problems are solved by a newly developed muscle-powered short-flight aircraft which, in a similar manner to cycling, has a high sporting value and will find many adherents, worldwide, as spare-time recreation for young and old. By means of the energy, which is stored in two rubber motors by pedalling and is transferred abruptly to two contrarotating propellers, the appliance lifts off the ground to a specific height, as though it had been catapulted. By regulating the speed of the airscrews by means of a freewheel and a built-in braking device, it is possible to regulate the height of the climb and to return smoothly and safely to the ground, as desired. The appliance can also be used for slimming purposes by the rubber motors just being charged up and then being allowed to unwind slowly.
